SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 370,235, datedSeptember 20, 1887.

(No model.)

To aZZ 2072 0771, it may concern:

Be it known that I, JOHN BRADY, a citizen of the United States, residingin the city and county of Philadelphia, State of Pennsylvania, haveinvented a new and useful Improvement in Sash Locks and Fasteners, whichimprovement is fully set forth in the following specification andaccompanying drawings, in which- Figure 1 represents a side elevation ofa sash fastener and lock embodying my invention. Fig. 2 representsahorizontal section in line at a, Fig. 1. Figs. 3, 4, and 5 are Views ofthe interior thereof on an enlarged scale. Fig. 6 represents a view of amodification, the parts being shown in locked condition.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention consists of a sash fastener and lock of novel construction,as will be hereinafter set forth.

Referring to the drawings, A represents a casing or box, which issecured to the meetingrail of the lowersash, and has fitted within thesame a sliding bolt, B, which is adapted to enter either of the openingsor keepers a in the window-frame, said bolt having a handle, B, whichprojects through the top of the casing,

whereby the bolt may be readily withdrawn from said opening. Bearingagainst said bolt is a spring, 0, for holding the same in lookingposition. To the inner side of the bolt B and at a right angle theretois secured a bolt, D, which is adapted to engage with either of thekeepers b, which are secured to the upper sash.

It will be seen that the lower sash may be readily fastened to thewindow-frame by means of the bolt B and the two sashes fastened togetherby means of the bolt D, thus providing security of fastening of bothsashes.

In order to lock the bolt B, there are fitted within the casing A thepivoted dog E and the tumbler F, the nose of said dog being adapted toengage with a shoulder, G, on the bolt. The tumbler has a lug, H, andthe dog has a lug, J, which engage with each other. A key is in sertedinto the casing, and as it is turned it engages with the heel of the dogand side of the tumbler.

Referring to Fig. 3, when the tumbler moves the lug H leaves the lug Jand the dog turns on its pivot, bringing its nose in engagement with theshoulder G, thus locking the bolt B and consequently the bolt D. Thetumbler under action of its spring returns to its first position,whereby the lugs H J re-engage, thus locking the dog. (See Fig. 4.) Inorder to unlock the bolts, the key is rotated in reverse direction, thetumbler moves, and the lug H leaves the lug J. The dog then turns on itspivot and its nose leaves the shoulder G, thus unlocking the bolts B D.The tumbler returns to its normal position, and the lug -I-I re-engageswith the lug J on the side opposite to that first named, so as to holdthe dog in unlocked position. (See Fig. 3.)

In Fig. 6 I show the bolt D separate from the bolt B, the dog E being ofdifferent form from the one shown in Figs. 2, 3, and 4, and having twonoses instead of one, so as to engage with the shoulders or projectionsG on each of the bolts B and D. The said dog in the lock in this figurehas a sliding motion, being fitted between a way or guide attached tothe back of the casing and the lower wall of the casing. The dog E andthe tumbler F have each a lug similar to lugs Jand H in the otherfigures, serving to keep the parts in fixed position until changed bythe action of the key on the dog and tumbler. In looking the bolts thekey acts upon the said dog and tumbler, so as to depress the end of thetumbler which is toward the bolt D and free the lug J, which is in frontof the lug H when the bolt is drawn within the casing. At the same timethe dog E is pushed forward, so that lug H takes a position on the rearside of the lug J, and there by locking the bolts D and B in position,as is readily seen. In unlocking, when the key is turned, the action ofthe dog is such that the bolt B is caused to be withdrawn within thecasing, while the bolt D is released, so that it may be readily operatedby hand or by aspring connected thereto. It will be seen that the effectis the same as previously set forthviz., the two bolts may be locked,thus fastening the two sashes to each other and to the window-frame in asecure manner.

Having thus described my invention, whatI claim as new, and desire tosecure by Letters Patent, is

1. A sash fastener and lock having two bolts,

B D, at a right angle to each other, a dog which engages with saidbolts, and a tumbler which locks said dog, the parts being combined and5 operating substantially as described. 7 2. A combined sash fastenerand lock having a spring-bolt, with a second bolt adapted to act atright angles thereto, a dog with a nose adapted to engage and lock saidspringbolt,

a tumbler operated by a key and having a lug [0 adapted to engage with alug on the said dog, and a spring normally adapted to keep the lugs onsaid dog and tumbler in engagement, all substantially as described.
